The OEM plug is copper NGK BKR6EYA11. Why doesnt it come with platinum or iridium nowadays? Is it better to change to platinum or iridium or should I just stick to OEM copper? How long will copper last? The manual doesnt state any change interval for sparkplugs.

Is copper the 'in' thing again? Reminds me of the timing chain then to timing belts and then back to timing chain again.
